Povzetek


Biološka spremenljivost je prisotna povsod v naravi. Vsebuje koristno informacijo, ki je navadno prezrta v navadno uporabljenih statističnih postopkih. Če hočemo izluščiti to informacijo je potrebno uporabiti posebne postopke. Biološko spremenljivost lahko opazujemo v lastnostih kot so velikost, barva, čvrstost itd., kjer je osnova zanjo skoraj vedno razlika v razvoju ali zrelosti vzorca analiziranih primerkov, ki jo povzročajo majhne notranje in okoljske razlike. Osnove ugotavljanja biološke spremenljivosti v naboru analiziranih primerkov so razložene brez poudarjanja matematičnih podrobnostih. Pojasnjen delež spremenljivosti je pri običajenm postopku med 60 in 80 %. Če upoštevamo biološko spremenljivost, se poveča na 95 %. V primeru, da odpravimo še napake meritve, lahko pojasnjen delež spremenljivosti povečamo na 99 %. Takšen način obdelave je dal zelo dobre rezultate v že objavljenih raziskavah razvoja barve jabolk med rastjo in hrambo ter pri meritvah čvrstosti paradižnika med shranjevanjem.

Ključne besede


biološka spremenljivost; biološki šift faktor; mešani učinek nelinearne regresije; indeksirana nelinearna regresija; barva jabolk; čvrstost paradižnika
